hi guys.

Right i have a 1989 2ltr twinspark 8 valve. rebuilt about 4 months ago. engine starts fine. runs fine, until you try to rev past 3000rpm, thens its starts surging and wont rev any more. have checked following, timing, variator, solenoid for variator, crank position sensor. please if anyone has struck this before help help help....

one though i had was when i put the engine in etc i had 2 problems. 1) The main fuel pump wire got caught under the carpet and grounded out, i since re routed it but could this have damaged ecu maybe...... 2) The starter motor connected fine first pop until this wire shorted, now it only clicks....i have to short out the main start relay under the bonnet to get it to turn over.

please if someone could help, as its so frustrating.

regards

James

You can wire the fuel pumps direct to eliminate any problems albiet temporarily. It sounds like its not getting enough fuel. So wire the fuel pumps direct then ensure the injectors are grounded correctly. See what happens!
